APPARATUS FOR CONVERTING Dl STlLLERY-SLOP INTO DRY FEED.

SPECIFICATION formingpart of Letters Patent No. 761,571, dated May 31,1904. Applicatioufileii October 12,1900. Serial No. 32,900. (No model.)

To all whom it may concern:

Be it known that we, CHRISTIAN ANDERSON.

of Peoria and State of Illinois, have invented certain new and usefulImprovements in Apparatus for Converting Distillery-Slop into Dry Feed;and we do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an apparatus for converting slop into a dryfeed forlive stock.

In our Letters Patent No. 653,645, issued:

July 30, 1900, we describe a very eflective method for separating thethin slop from the.

thicker portions, consisting of a system of settling-tubs,filter-presses, and other devices, and in this application WG'dGSiIG'bOshow the mechanical apparatus for accomplishing the purposes set forthinthat patent. The separation of the thin slop from the thicker solidparts can of course be accomplished by mechanical devices-:such, forinstance, as filterpresses, filter-boxes, strainers, seives, orcentrifugal machines. These methods of separation, however, are too wellknown to require elucidation here.

Our object is to make this separation andthen subject the thinner liquidslop to vacuum process while the thick solid portion is finished onsuitable driers. The syrup resulting from the thinportion may be mixedwith the thick portion before it is dried or mixed with chaff or coarsefeed or dried separately or mixed or run into the fresh slop and againpassed through the filter-presses or converted into dry feed through anysuitable process for this purpose.

Another object of this invention is to employ a machine for breaking thefeed from the pressesinto fine particles, so as to make it more suitablefor the drier and avoid lumps 'and Wet feed in the finishedproduct.

the meshes of the cloth in the separator whenever in the process ,of themanufacture they again reach that machine, thereby producing feed ofgreat uniformity.

In the drawing our improved apparatus is shown in elevation," thevarious elements thereof being distributed upon several floors in orderto have them in proper relation to each other, although otherarrangements of course are possible.

A indicates a tub for receiving slop through a pipe (0 from thedistillery.

Bis a filter-press, to which the slop fro the said tub A is raised bymeans of. a pump C and pipe D. Thesaid filter-press may of course besubstituted by any equivalent of well-known devices to serve the samepurpose. A receiver E for thin slop is located beneath the filter-pressand receives the extracted portion from the latter through a pipe F.

Gr indicates a breaker which receives the dry materials from thefilter-press through a conveyer Hand spout I. This machine Gr reducesthe cakedportions to small particles before being allowed to enter thedrier J through spout K, so that they be quickly and thoroughly driedduring the passage through the said drier J. An elevator L receives thedried portions from the drier J and carries from said separator arecarried through a spout- Q into a reduction-machine R and there reducedto fine particles and from thence into a hopper S. Beneaththe hopper isa conveyer T, which receives the material through a gate or valve U, thelatter being provided to regulate the bulk of material passing fromthehopper into the conveyer. Connected with the receiver E through a pipe Eis a vacuumapparatus V, into which the thin slop from said receiver isrun. Said apparatus may be of any approved. form and used either singlyor in multiple. The syrup derived from this apparatus is conveyedthrough a pipeW to the conveyer T, where it is mixed with the materialfrom the hopper S. The amount of the dried portion to be used isregulated by the valve U, whereby the desired mixture may be had. Amixer Xbeneath the conveyer serves to more fully mix the material beforeit is allowed to pass into the slop-tub A.

From the foregoing it will be seen that the slop from the distillery isfirst put under pressure to separate the thin and thick portions, thelatter being passed to the drier, but first reduced by the breaker G.From said drier the dry feed is run over the separating-machine M, thefinished material, or that which passes through the cloth of theseparator, is carried to a storage-compartment, while the coarsetailings are run to the hopper S to be mixed with the syrup from thevacuum apparatus for further treatment, as described, or are run overthereduction-machine before such mixing. The mixed portion may becarried direct through the drier to carry off the moisture or run intothe slop-tub A to be again passed through the filter-press and thisprocess continued until all is worked into dry feed.

It is evident that the above process may be very materially altered andvaried and still the final results be the same. The breaker, theseparator, the mixing-conveyer, hopper, and mixer may all be dispensedwith. The mixing may be done in tub A or any other receptacle for suchpurposes. Additional tubs and leaders may be introduced to facilitatethe work or meet construction of buildings. However, none of such thingsinterfere with the treatment of the thin slop in a vacuum for thepurpose of converting it into dry feed. The entire vacuum apparatus maybe dispensed with and the breaker G or the reduction-machine R willstill perform the service claimed for them.

The use of a breaker introduced so as to break up the thick solidslop-cakes before they enter the drier, a reduction-machine to grind thetail ends from the separator, the use of a vacuum apparatus inslop-drying are as far as we know new and have not been'used inslopdrying machinery before our invention.

We claim 1. An apparatus for making dry feed from distillery-slopconsisting of means for separating the thin from the thick slop, avacuum apparatus for receiving the thin slop from the separator anddriving off the moisture therefrom, an apparatus for receiving anddrying the thick portions from the separator, a reel for receiving andseparating the fine material from the coarse after leaving the drier,means for conveying said material from the drier to the said reel, meansfor reducing the coarse material from said reel, a mixer for receivingthe ground material from said reducing means and the resulting syrupfrom the vacuum apparatus, means for conveying the syrup to such mixerfrom the said vacuum apparatus and means also for conveying the reducedmaterial of the said reducing means to the mixer, the mixed materialbeing incorporated with the untreated slop coming from the distillery,the finer portions from the reel constituting the finished product.

2. An apparatus for making dry feed from distillery-slop consisting ofmeans for separating the thick from the thin slop, a vacuum apparatusfor receiving the thin slop and driving off the water therefrom to leavea residue, means for conveying the residue to the untreated slop fromthe distillery, means for reducing .the thick material from theseparator, means for drying the material from the reducer, a reel forscreening the dried material from the drier, means for conveying thesaid material from the latter to the former, a second reducing means forreceiving and reducing the coarse material from the reel, means forcarrying the material from the reel to the reducing means, a mixer forincorporating the reduced material from the reducing means with theresidue of the vacuum apparatus, means for conveying the material fromthe reducing means to the mixer, the mixed product being returned to theuntreated slop from the distillery.

3. An apparatus for making dry feed from distillery-slop consisting ofmeans for separating the thick from the thin slop, an evaporatingapparatus for receiving the thin slop and driving off the watertherefrom, the residue therefrom being returned to the untreated slop, abreaker for reducing the thick solid portions of the material as itcomes from the separator, means for drying the said reduced material, areel for screening the dried material to separate the liner portions asthe linished product, means for conveying the dried product to the reel,a reducer for the coarse portions from the reel, a mixing device forincorporating the residue of the evaporating apparatus with the reducedcoarse portions from the reel, means for conveying the material from thereel to the mixer, and means also for conveying the residue of theevaporating apparatus to such mixer substantially as set forth.

In testimony whereof We afiix our signatures in presence of twoWitnesses.
